Document Type and Number:

WIPO Patent Application WO/2018/139628

Kind Code:

A1

Abstract:

Provided is: a terminal material for a connector terminal, which uses a copper or copper alloy substrate and is free from the occurrence of electrical corrosion, said connector terminal being crimped to an end of an electric wire that is formed of an aluminum wire rod; and a terminal which uses this terminal material. According to the present invention, a zinc layer 4 that is formed of zinc or a zinc alloy and a tin layer 5 that is formed of tin or a tin alloy are sequentially laminated in this order on a substrate 2 that is formed of copper or a copper alloy. With respect to the zinc layer and the tin layer, the adhesion amount of tin contained in the whole layers is from 0.5 mg/cm2 to 7.0 mg/cm2 (inclusive) and the adhesion amount of zinc contained in the whole layers is from 0.07 mg/cm2 to 2.0 mg/cm2 (inclusive), and the content percentage of zinc in the vicinity of the surface is from 0.2% by mass to 10.0% by mass (inclusive).
